relation thereto. The blade 13 is adapted to This invention relates tothe type of scraping and cutting'tools comprising generally ahandlecarryingmembers between which a blade is removably clamped. j Itschief object is the provision of a simple tool or holder'of thischaracter which'permits the ready application and removal of the bladeand which can be cheaply manufactured.

Anotherlobjectis to so constructthe-tool that one of its blade-clampingmembers may perform the additional function of a guar when the device isnot in use. V

In the accompanying drawings Figure 1 is a perspective view of thebladeholder, showingthe same adjusted to expose the edge of the blade.Figure 2is asimilar View with the parts in position to apply or removeablade. Figure 8 is a perspective view of the clamping platen Figure 4is a similar view of'a type of blade which may be clamped in the holder.Figures 5 and 6 are transverse sections of the head of the holder,showing different adjustments of the clamping plate.

Similar characters of reference indicate corresponding parts throughoutthe several views.

The tool comprises a handle 10 terminating at its front end in a fiatcross head 11, and a clamping plate 12 imposed on the cross head andhaving the same general dimensions as the head. Between these members asuitable scraping or cutting blade 13 is held. Old or new razor bladesmay be used for this purpose, the blade shown in the drawings being ofthe Well-known double-edge type with three holes.

The head 11 has a central opening 1 1 adapted to register with thecorresponding hole of the blade and a pairof lugs or stops 15 located onthe face of the head on opposite sides of said opening through the endholes of the blade to hold it against backward and endwise movement onthe handle-head. These lugs are preferably struck up from the headandarranged to face forwardly, as shown, with their free end portionsdisposed substantially horizonta]. or parallel to the cross head inspaced and adapted to passv the lugs 15 overlying the blade.

11, andon opposite sides of the stud said plate has transverse slots orapertures 18,

adapted to receive the lugs 15, to hold the plate froinlateral andbackward displacement on the handle-head. These slots extendbeyond'the'front and rear edges of the central stud 16 and are of alength substantially twicethat of the lugs 15.

' J A lever 19 fulcrumed on the handle 10 and engaging the plate 12serves to "clamp the blade securely between these parts and to keeptheir retaining members interlocked. In the preferred constructionshown, this lever is pivoted between its ends to the handle by a pin20located adjacent to and centrally of the plate 12, the short upper armof the lever being offset and normally'over lapping said plate, whileits long lower arm overlies and bears against the face of the handle. Toapply a blade to the holder, the clamping lever is swung crosswiseofthe'handle, as shownin Figure 2, and the clamping plate 12 is removedfrom the head 11. A blade is then engaged with the lugs 15, theclamping-plate is replaced to interlock its stud '16'with the blade andthe slots 18'with said lugs andthe lever isturned parallel with thehandle, thus locking the clamping plate one of its longitudinal edgesthan the other,

as shownin Figure 3. 'By thisarra-ngement, upon bringing the edge of theplate nearest the slots opposite the front edge of the handle-head, thecutting edge of the blade is uncovered for service, as shown in Figures1 and 5, with the free edges of the lugs 15 abutting against one end ofthe slots 18 in the clamping plate 12, While upon reversing the platefrom this position, its other edge extends beyond the cutting edge ofthe blade and covers it as shown in Figure 6 with the freeedges' of saidlugs 15 abutting against the opposite ends ofsaid slots, therebyprotecting the hands when the tool is not in use. In either position ofthe clamping plate its stud 16 engages the opening 14in the cross head11 and one end or the other of the slots 18 abut against the lugs 15,thus positively holding the clamping plate against accidentaldisplacement. V

This improved tool or holder is especially serviceable as a scraper, forexample, for removingpaper from walls or paint from various surfaces,but it is also useful as a V cutter.

a a blade-clamping plate imposed on said head and having a stud arrangedto engage an opening of the blade and the opening of said head, andapertures to receive said lugs, the latter constituting stops foralining the blade on the cross head to bring its opening into registerwith the cross head opening, and a clamping lever fulcrumed between itsends on said handle and overlapping said clamping-plate.

2 A blade holder of the character described, comprising a pair ofsuperposed blade-clamping members and means for clamping them together,one of said members having a stop-lug and the other being reversible andhaving a transverse slot engaging said lug and of a length substantiallytwice that of the engaging portion of the lug, said slot being arrangednearer one longitudinal edge of said slot-ted member than the other, touncover the cutting edge of the clamped blade in one position of thereversible member and cover said edge in the other position of themember, one end of the slot engaging the lug in one position of thepartsand the other end of said slot engaging its lug in the other position ofthe parts.

8. A blade holder of the character described, comprising a handle havinga cross head, said head being provided centrally with an opening and onopposite sides of said opening with blade-engaging lugs, said lugsfacing forwardly with their free end portions in spaced parallelrelation to the cross head, a blade-clamping plate imposed on said headand having a stud arranged to engage an opening of the blade and theopening of said head and also having transverse slots to receive saidlugs, said clamping-plate being reversible on said cross head and itsslots being located nearer'one longitudinal edge a plurality of aliningopenings therein, said" cross head having an opening therein andforwardly-facing blade-engaging lugs struck from its top side and havingtheir free end portions disposed in spacedparallel relation to the crosshead, such. spa cebeing sufficient to receive the contiguous portions ofthe blade beneath said lugs, the clamping platehaving a stud projectingfrom its bottom side for engagement with one of the blade-openingsandsaid crosshead opening and also having transversely-elongatedopenings for receiving the cross head lugs and against one end of whichsaid lugs are adapted to abut, and means mounted on the handled memberfor clamping the other member thereto.
